Why is there no sound when locking the Haval Big Dog?
2 Answers
It is because the settings are not properly configured, and hidden settings need to be adjusted. Below is an introduction to the Haval Big Dog: 1. Exterior: (1) The side profile of the vehicle features mostly bold and hard lines, with a square and robust appearance. The front doors come with a keyless entry function, and the roof rack and side steps are also fully equipped. (2) The exterior mirrors are equipped with lane change assist warning lights, and the entire housing is designed in black. (3) The rear design also has notable highlights, with protruding rear bumpers similar to the front and L-shaped smoked taillights that give a wild appearance. 2. Configuration: (1) The 2.0T model will be equipped with the fifth-generation Haldex four-wheel-drive system and a rear axle differential lock with dog teeth. (2) The 2.0T engine delivers a maximum power of 204 horsepower and a peak torque of 320 N·m, paired with a 7-speed dual-clutch transmission.
I also have this issue with my Haval Big Dog. The lack of sound when locking the car is mostly due to the alert tone setting being turned off. Don't rush to repair it yet. First, open the central control screen, go to the vehicle settings option, and check if the lock alert tone option is turned off. Last time, after a car wash, the attendant accidentally turned off this function. If the setting is on but there's still no sound, it might be that the buzzer at the front of the car is broken. This part is located in the engine compartment and is prone to water ingress and short circuits on rainy days. Alternatively, it could be due to low battery voltage causing system malfunctions, which might also be accompanied by issues like difficulty starting the car. In this case, you should quickly check the battery's health. If it's really a hardware failure, replacing the buzzer isn't expensive—just around a hundred yuan, and it can be done in half an hour at a regular repair shop. Trying to dismantle it yourself might make the wiring worse.
